This disclosure relates to systems, apparatus, and methods for documenting a code blue scenario in which a subject is undergoing resuscitation.
Patient safety is one of the most important challenges facing today's healthcare. There are approximately 2.5 million deaths in the U.S. each year, about a third of which occur in acute care hospitals. Unless there are “do-not-resuscitate” advanced directives in place, patients who die in a hospital most likely have undergone one or more resuscitation attempts known as “code blue.” Code blue is used by hospitals to describe a scenario in which a patient with cardiac or respiratory arrest requires stat medical intervention (i.e., resuscitation). Medical errors occur in healthcare every day. In code blue scenarios, medical errors may be likely to occur, which can cost lives. Common errors in cardiopulmonary resuscitation (CPR) may include slow chest compression rates, shallow chest compression depths, hyperventilation, long pauses in CPR before shock delivery, delivery of electrical defibrillation for nonshockable rhythms, medication errors, failure to follow resuscitation guidelines (e.g., advanced cardiovascular life support (ACLS), pediatric advanced life support (PALS), and/or other guidelines), and/or other errors.
Studies have found conventional paper-based documentation practices of code blue scenarios may be inaccurate, often misreporting intervention delivery times, missing their delivery entirely, and/or making other documentation errors. Paper-based code blue records may commonly have missing time data, include use of multiple timepieces for recording time data during the same event, and convey a wide variation in coherence and precision of clocking devices. For example, the documentation of time in emergency events has been shown to vary significantly, by as much as nineteen minutes, depending on which clocking devices are used. Furthermore, incomplete and inaccurate documentation of code blue scenarios are frequently a source for medicolegal disputes.
Exemplary implementations may provide feedback (e.g., coaching) to caregivers during a code blue scenario, as well as complete and accurate documentation of code blue scenarios, which may facilitate quality improvement of resuscitation in practice, enhance in patent safety, and protect healthcare professionals against lawsuits. Some implementations provide an electronic apparatus for providing feedback to caregivers and complete documentation of code blue scenarios. This apparatus may be referred to as a “BlueBox.” According to one implementation, the apparatus may include a five by ten centimeter elongated patch configured to be placed next to the mid-sternum on the left. Other configurations are contemplated. The apparatus may be configured to provide feedback to caregivers related to, as well as provide complete capture of, all code blue events including vital signs of a subject (e.g., a patient or other individual undergoing resuscitation), cardiac rhythm, verbal orders, execution of the orders, chest compression, cardioversion/defibrillation, procedures, medications, labs, and/or other events. The apparatus may enhance the safety of subjects undergoing CPR. The apparatus may provide electronic code blue records that can be useful for electronic medical record (EMR) documentation, education, and quality improvement.
The apparatus may include multiple sensors embedded in a micro-electronics platform. The sensors may include electrocardiogram (ECG) sensors, one or more accelerometers (e.g., a tri-axial accelerometer), a temperature sensor, an impendence sensor, one or more acoustic sensors, one or more sensors configured for detecting oxygen saturation (SpO2) (e.g., pulse oximeter sensors), and/or other sensors. In some implementations, all of the sensors may be integrated into a volume with a four centimeter diameter and eight millimeter thickness. Feedback may be given, and vital signs and audio information may be simultaneously recorded with corresponding time stamps and/or other information. Security measures may be implemented to protect the recorded information. An enclosure and contact surface of the apparatus may be designed to withstand pressure from chest compressions and/or voltages from cardioversion and defibrillation.
An “electronic code blue sheet” and/or feedback user interface may be provided to display the feedback, and/or the code blue events recorded by the apparatus. In accordance with some implementations, the user interface may be provided by an app suitable for one or more platforms including Apple iOS™ platform, Android™ platform, Microsoft Windows™, and/or other platforms. The app may run on one or more computing platforms associated with a caregiver, a medical facility and/or other medical providers, medical equipment in the environment where the code blue events occur, and/or other computing platforms. The app may receive information from sensors of the apparatus, retrieve information recorded by the apparatus, receive and/or retrieve information from a server and/or other processing devices, and/or perform other operations via a wireless connection, and automatically display the feedback, the code blue events chronologically with time stamps, and/or other information, in some implementations. The user interface may provide zoomable views of the feedback, the vital signs, and/or other information. The user interface may facilitate communication of audio instructions, playback of other audio information, and/or other operations. In some implementations, a trained transcriptionist may annotate additional events, such as procedures and medications, based on the voice recordings. This annotation may be performed automatically with the aid of voice recognition technology, in some implementations. The electronic code blue sheet may be exported (e.g., as a portable document file (PDF) and/or other electronic document formats) so that the code blue sheet can be printed for paper medical record, or for uploading to EMR.

Components of system 100 may continuously record important vital parameters of a subject undergoing CPR, procedures such as chest compression and defibrillation, and all verbal communications among the code blue team members such as orders, responses, medications, lab results, and/or other verbal communications. Proper documentation of code blue scenarios may facilitate detailed reviews of CPR events for quality improvement, thus enhancing patent safety. Proper documentation may protect healthcare professionals against lawsuits which might otherwise be due to incomplete or inaccurate documentation. Properly documenting care in a patient's medical records is essential and, in the event of a lawsuit, provides evidence that the care that was provided met professional standards.
In one exemplary implementation, system 100 may include an apparatus shaped as a disk having a diameter of four centimeters and a thickness of one centimeter, housed in a ten by five centimeter patch shaped as a big Band-Aid. The apparatus may be configured to be placed on the left mid chest, over the fourth intercostal space between the left sternal border and left nipple, at the beginning of a code blue scenario. There may be no control buttons or other mechanisms on the apparatus. Instead, the apparatus may power on and begin recording responsive to a protective cover being removed. This may be achieved using a magnetic switch, according to some implementations. The apparatus may power off and stop recording responsive to the apparatus being removed from the subject. The apparatus may be configured to prevent unauthorized removal of any internal memory and/or tampering with recorded information.

The feedback interface 113 may be coupled to, formed by, formed in, or otherwise attached to enclosure 108. In some implementations, the feedback interface 113 may be the same as or similar to feedback interface 322 (shown in
In some embodiments, the feedback interface 113 may be at least partially formed in, on, or by a surface of enclosure 108 that is visible to the caregivers (e.g., a surface that is not adhered to the subject), and/or other surfaces. For example, the feedback interface 113 may be formed on a surface of enclosure 108 opposite a surface including a protective cover and/or adhesive of the system 100, on an edge surface of enclosure 108 visible to caregivers, and/or other surfaces. In some embodiments, one or more portions of the feedback interface 113 may be formed on different surfaces of enclosure 108. For example, the display screen 115, the speaker 119, and/or one or more indicator lights 117 may be formed on a larger surface of enclosure 108 opposite the protective cover, and one or more other indicator lights, and/or other components may be formed on a smaller edge surface of enclosure 108. It should be noted that this description of the feedback interface 113 is not to be considered limiting. The feedback interface 113 may or may not include all of the components listed above (e.g., the feedback interface 113 may comprise only indicator lights 117 and the speaker 119, only the indicator lights 117, only the display screen 115, only communications components of communications interface 118, etc.), and individual components may be located anywhere in, on, or otherwise coupled to enclosure 108 that allows the system 100 to function as described herein.
Feedback interface 113 may be configured to provide real-time and/or near real-time feedback to the caregivers during a code blue scenario. In some embodiments, the feedback may be provided in textual and/or graphical form via the display screen 115, via an app running on personal computing platform 104, and/or other components. In this example, the feedback may be provided by displaying textual instructions, displaying pictures and/or other images, and/or displaying other information. Displaying pictures and/or other images may include displaying annotated pictures or images that instruct (e.g., via arrows and/or other notations in the pictures and/or images) caregivers to perform specific actions, and/or other displays.
In some implementations, the feedback may be provided by lighting one more indicator lights 117 of different colors, lighting one or more indicator lights 117 with different patterns and/or frequencies, and/or by providing other lighting (e.g., lighting virtual lights displayed by the app running on personal computing platform 104). In this example, lights of different colors may correspond to different recommended actions, an intensity and/or other relative level of a recommended action (e.g., green means less intense, yellow means more intense, and red means most intense), and/or other information. A grid and/or other row(s) of lights may be lit in a specific shape or other pattern to indicate specific feedback. Lighting intensity (e.g., brightness) may be changed to indicate specific feedback. Indicator lights 117 may be controlled to blink or flash with specific patterns to indicate specific instructions.

For example, the speaker may instruct a caregiver “begin CPR” or provide other commands. In some implementations, the speaker 119 may provide beeping sounds and/or other noises that correspond to specific actions, an intensity of the specific actions, and/or other information. For example, the speaker 119 may provide a first sound that indicates a caregiver should start CPR, and additional sounds that help the caregiver pace compressions. In this example, the speaker 119 may adjust an intensity (e.g., the volume) of the sounds to cause the caregiver to perform deeper or shallower compressions, or make other adjustments to the CPR provided.
In some implementations, the feedback interface 113 may be and/or include one or more components (e.g., communications interface 118) configured to communicate real-time and/or near real-time feedback to the caregivers during a code blue scenario via one or more computing platforms (e.g., personal computing platform 104) remote from the apparatus 102. For example, the feedback interface 113 may be and/or include one or more components configured to communicate feedback to caregivers via one or more personal computing platforms 104, one or more computing platforms associated with one or more items of medical equipment proximate to a location where a patient is undergoing resuscitation, one or more computing platforms configured to record and/or present medical records, one or more computing platforms associated with a medical services provider and/or care facility, and/or other computing platforms. For example, in some implementations, the feedback may be provided via Bluetooth components included in the feedback interface 113 linked to an iPad or other mobile device or computer. In some implementations, for example, the apparatus 102 itself may be able to process the analysis and provide feedback directly via one or more displays and/or indicators of the feedback interface 113 device (e.g., as described above). In some implementations, for example, the apparatus 102 may be coupled to a (e.g., cloud) server (e.g., server 106, feedback processor 109, etc.) and stream data to the server in real-time or near real-time, which may process received data, analyze results, and send them back to the apparatus 102 to show resuscitation recommendations. In some implementations, for example, the apparatus 102 may be coupled to the (e.g., cloud) server (e.g., server 106, feedback processor 109, etc.) and stream data to the server in real-time or near real-time, which may process received data, analyze results, and send them back to the personal computing platform 104 and/or other computing platforms to show resuscitation recommendations.
In some implementations, the feedback interface may include a timer 121.

In some implementations, the timer 121 may be activated responsive to one or both of the apparatus 102 being removably adhered to the subject's chest or an adhesive cover being removed from the enclosure 102, for example. In some implementations, the timer 121 may be activated responsive to collapse of the subject, responsive to a start of CPR and/or other resuscitation operations, responsive to defibrillation, and/or responsive to other operations. In some implementations, as described below, the timer 121 may be activated by computer program instructions 138 and/or time stamping component 140.

The electronic storage 114 may be disposed within enclosure 108. The electronic storage 114 may be configured to store and provide access to information conveyed by the signals provided by sensor bank 112, information determined by feedback processor 109, and/or other information. According to some implementations, apparatus 102 may be assigned a unique serial number and a security code for accessing information stored by electronic storage 114. To access the stored information using a given personal computing device (e.g., personal computing platform 104), the given personal computing device may be required to be paired with apparatus 102 via a Bluetooth link and/or other communicative connection, in accordance with some implementations.
In some implementations, a patient's identifiers may be recorded by virtue of a user verbally identifying the patient's name, a hospital ID number, a date of birth, and/or other patient information. In some implementations, apparatus 102 may be configured to wirelessly retrieve information including patient information from other electronic medical devices. The apparatus 102 may be configured to obtain patient information by scanning visual marks (e.g., barcode, QR code, and/or other visual marks), by imaging the patient's ID band, by a keypad, and/or by other techniques.
The communications interface 118 may be disposed within enclosure 112. The communications interface 118 may be configured to communicate with one or more other components of system 110 by wireless connections and/or wired connections. The communication interface 118 may be configured to transmit one or more of signals provided by sensor bank 112, information conveyed by the signals provided by sensor bank 112, information stored by electronic storage 114, information received from feedback interface 113, information received from processor(s) 116, and/or other information. The communications interface 118 may be configured to receive information from one or more other components of system 100. For example, the communications interface 118 may be configured to receive feedback (and/or information related to the feedback) determined by feedback processor 109, transmit (e.g., via Bluetooth components, etc., as described herein) the information received from feedback processor 109 to personal computing platform 104 for communication to a caregiver, and/or perform other operations. In some implementations, the communications interface 118 may be configured to transmit received feedback to feedback interface 113 for provision to caregivers. According to some implementations, communications interface 118 may be compatible with one or more of a Bluetooth standard, a Wi-Fi standard, an ANT or ANT+ standard, a near-field standard, wireless data communication protocols, and/or other communications standards.
The feedback processor 109 may formed by and/or in one or more individual stand alone processors 109, one or more servers 106, one or more personal computing platforms 104, the apparatus 102, and/or other components of the system 100. The feedback processor 109 may be configured to generate real-time and/or near real-time feedback for caregivers based on the information in the signals from the sensor bank 112 and/or other information. The real-time and/or near real-time feedback may comprise a recommendation to begin resuscitation, adjustments that should be made to ongoing resuscitation, and/or other feedback. In some implementations, the generated real-time and/or near real-time feedback may comprise recommendations that one or more actions taken by taken by the code blue caregiver team during the code blue scenario such as recommending one or more of chest compressions be performed on the subject during resuscitation, cardioversion procedures and/or defibrillation procedures be performed on the subject during resuscitation, medications be administered to the subject during resuscitation, endotracheal intubation be performed on the subject, artificial respiration be provided to the subject during resuscitation, vascular accesses (e.g., intravenous lines, intra-osseous lines, arterial lines, and/or other accesses) be created, surgical procedures be performed, laboratory tests be performed, and/or other actions be taken by the code blue caregiver team.
By way of a non-limiting example, in some implementations, the feedback processor 109 may be configured such that the real-time feedback may comprise adjustments that should be made to ongoing resuscitation. Such adjustments may comprise recommended changes to one or more of a compression rate (e.g., compressions per minute), a compression depth (e.g., cm), a pause between compressions (e.g., sec), or a compression interval of cardiopulmonary resuscitation (CPR) chest compressions performed on the subject during the code blue scenario. For example, the rate and depth of chest compression may be detected based on output signals from the chest compression sensor 132. The feedback processor 109 may be configured to determine whether the rate and/or depth of chest compression are within a predetermined amount of a target rate and/or depth of chest compression and/or meet other target criteria. In some implementations, the predetermined amount may be an absolute value, a percentage, and/or other predetermined amounts. In some implementations, the feedback processor 109 may be configured to determine whether the rate and/or depth of chest compression are within a predetermined amount of 10%, 20%, 50%, and/or other percentages of the target rate and/or depth of chest compression. In some implementations, responsive to the rate and/or depth being more than 20% (for example) different than the target rate and/or depth, the feedback processor 109 may cause the feedback interface 113 to provide feedback to the caregiver performing CPR. The feedback processor 109 may control the speaker 119, the indicator lights 117, and/or other components of the feedback interface 113 to provide feedback to the caregiver that causes the caregiver to adjust the way the caregiver is performing CPR on the subject. In some implementations, the target rate and/or depth of chest compression may be determined at manufacture of the system 100, received and/or adjusted via input to the personal computing platform 104, determined by the feedback processor 109 and/or other components based on information from the external resources 152 and/or other sources, determined by the server 106, and/or determined in other ways.
In some implementations, generating the real-time feedback based on the information in the signals from the sensor bank may comprise determining time elapsed since a collapse of the subject. The time elapsed since a collapse may be determined to be at least some minimum amount of time. The feedback processor 109 may be configured to determine time elapsed since collapse responsive to the information in the signals from the sensor bank indicating ventricular fibrillation and no respiratory movement in the subject. In some implementations, this minimum amount of time may be about one minute. In some implementations, this minimum amount of time may be about two minutes. In some implementations, this minimum amount of time may be about three or more minutes.
In some implementations, the feedback processor 109 may be configured such that the real-time feedback may comprise a recommendation to begin chest compressions on the subject. The recommendation to begin chest compressions on the subject may be determined responsive to the time elapsed since collapse of the subject being at least one minute (for example) and/or another predetermined amount of time, the information in the signals from the sensor bank 112 indicating no respiratory movement, the information in the signals from the sensor bank 112 indicating no pulse in the subject, and/or other information. For example, the recommendation to begin chest compressions may be determined responsive to an ECG (e.g., part of sensor bank 112 as described herein) which shows ventricular fibrillation and respiration sensors (e.g., 124) and/or chest movement sensors (e.g., 126) that show no respiratory chest movement. In this example, the feedback processor 109 may cause the speaker 119 to ask a caregiver whether the subject has a pulse. If the caregiver responds that there is no pulse (detected by the verbal communication sensor 136), the feedback processor 109 may control the speaker 119, the indicator lights 117, and/or other components of the feedback interface 113 to recommend beginning chest compressions.
In some implementations, the feedback processor 109 may be configured such that the real-time feedback may comprise a recommendation to shock or defibrillate the subject. The recommendation to shock or defibrillate the subject may be determined responsive to a time elapsed since a start of chest compressions being at least three minutes (for example) and/or another predetermined amount of time, the information in the signals from the sensor bank 112 indicating ventricular fibrillation, the information in the signals from the sensor bank 112 indicating no pulse in the subject, and/or other information. For example, after three minutes (for example) of chest compressions (e.g., as detected by the chest compression sensor 132), an ECG rhythm may be detected (e.g., by the cardiac rhythm sensor 122). Responsive to the ECG rhythm remaining Ventricular tachycardia (Vtach)/Ventricular fibrillation (Vfib), the feedback processor 109 may cause the speaker 119 to ask a caregiver whether the subject has a pulse or determine whether there is a pulse based on output signals from the heart rate sensor 120. If the caregiver responds that there is no pulse (detected by the verbal communication sensor 136) or if the output signals do not show a pulse, the feedback processor 109 may control the speaker 119, the indicator lights 117, and/or other components of the feedback interface 113 to recommend shock or defibrillation.
In some implementations, the real-time feedback may comprise a recommendation to inject the subject with epinephrine. The recommendation to inject the subject with epinephrine may be determined responsive to a time elapsed since a start of chest compressions being at least five minutes (for example), the information in the signals from the sensor bank 112 indicating ventricular fibrillation, the information in the signals from the sensor bank 112 indicating no pulse in the subject, and/or other information. For example, after five minutes (for example) of chest compressions (e.g., as detected by the chest compression sensor 132), an ECG rhythm may be detected (e.g., by the cardiac rhythm sensor 122). Responsive to the ECG rhythm remaining Vtach/Vfib, the feedback processor 109 may cause the speaker 119 to ask a caregiver whether the subject has a pulse or determine whether there is a pulse based on output signals from the heart rate sensor 120. If the caregiver responds that there is no pulse (detected by the verbal communication sensor 136) or if the output signals do not show a pulse, the feedback processor 109 may control the speaker 119, the indicator lights 117, and/or other components of the feedback interface 113 to recommend injecting the subject with epinephrine.
In some implementations, the subject may be receiving positive pressure ventilation during the code blue scenario. In such implementations, the feedback processor 109 may be configured such that the real-time feedback may comprise a recommendation to adjust a ventilation pressure, a ventilation rate, and/or other ventilation parameters. The recommendation to adjust the ventilation pressure and/or the ventilation rate may be determined based on information in the signals from the sensor bank 112 related to a rate and depth of chest rise in the subject, and/or other information. For example, the rate and depth of chest rise may be detected based on output signals from the respiration sensor 124, the chest movement sensor 126, or other sensors. The feedback processor 109 may be configured to determine whether the rate and/or depth of chest rise are within a predetermined amount of a target rate and/or depth of chest rise and/or meet other target criteria. In some implementations, the predetermined amount may be an absolute value, a percentage, and/or other predetermined amounts (e.g., similar to those described above). In some implementations, responsive to the rate and/or depth being more than the predetermined amount different than the target rate and/or depth, the feedback processor 109 may cause the feedback interface 113 to provide feedback to the caregivers. The feedback processor 109 may control the speaker 119, the indicator lights 117, the display screen 115, and/or other components of the feedback interface 113 to provide feedback to the caregiver that causes the caregiver to adjust the way the ventilation is provided to the subject. In some implementations, the target rate and/or depth of chest rise is determined at manufacture of the system 100, received and/or adjusted via input to the personal computing platform 104, determined by the feedback processor 109 and/or other components based on information from external resources 152 and/or other sources, determined by the server 106, and/or determined in other ways.
In some implementations, the feedback processor 109 may be configured such that generating the real-time feedback based on the information in the signals from the sensor bank 112 may comprise a machine-learning and/or model based analysis of the information in the signals from the sensor bank 112. The machine-learning and/or model based analysis may comprise determining which future actions taken by caregivers during resuscitation would improve a likelihood of recovery from the code blue scenario by the subject and/or determining other information. The machine learning and/or model based analysis may comprise generating the real-time feedback based on the predictions and/or other operations.
In some implementations, the machine learning and/or model based analysis may comprise a model based portion configured to reduce complexity by efficiently solving well-known parts of the analysis, and a machine learning portion configured to discover solutions. In some implementations, the model based portion may be used to determine whether certain target variables, such as chest compression rate and depth, are within or out of predetermined recommended parameter ranges. In some implementations, the model based portion may be augmented by deep machine learning. In some implementations, the machine learning and/or model based analysis may include training based on information from several individual patients (e.g., 100's, 1000's, and/or 100000's of patients).
In some implementations, the machine learning and/or model based analysis comprises an offline training mode during which the feedback processor 109 obtains training data comprising information from prior code blue scenarios including information from the sensor bank 112, corresponding feedback provided to caregivers, corresponding outcome information for patients, and/or other information for training machine learning algorithms and/or other electronic models used in the analysis. In some implementations, the feedback processor 109 may be configured such that the machine learning and/or model based analysis is performed by one or more machine learning algorithms, one or more neutral networks, and/or other models. As an example, neural networks may be based on a large collection of neural units (or artificial neurons). Neural networks may loosely mimic the manner in which a biological brain works (e.g., via large clusters of biological neurons connected by axons). Each neural unit of a neural network may be connected with many other neural units of the neural network. Such connections can be enforcing or inhibitory in their effect on the activation state of connected neural units. In some embodiments, each individual neural unit may have a summation function which combines the values of all its inputs together. In some embodiments, each connection (or the neutral unit itself) may have a threshold function such that the signal must surpass the threshold before it is allowed to propagate to other neural units. These neural network systems may be self-learning and trained, rather than explicitly programmed, and can perform significantly better in certain areas of problem solving, as compared to traditional computer programs. In some embodiments, neural networks may include multiple layers (e.g., where a signal path traverses from front layers to back layers). In some embodiments, back propagation techniques may be utilized by the neural networks, where forward stimulation is used to reset weights on the “front” neural units. In some embodiments, stimulation and inhibition for neural networks may be more free-flowing, with connections interacting in a more chaotic and complex fashion.
As described herein, the machine learning and/or model based analysis may be performed by feedback processors 109 (e.g., stand alone devices, and/or included in the server 106, the personal computing platform 104 (e.g., an iPad and/or other personal computing platforms), and/or other devices) and/or other components based on information transmitted from the apparatus 102. Once analyzed, in some implementations, the personal computing platform 104 (e.g., iPad) may display the results and recommendations.

The recommendation to begin chest compressions on the subject may be determined responsive to the time elapsed since collapse of the subject being at least one minute (for example), the information in the signals from the sensor bank indicating no respiratory movement, the information in the signals from the sensor bank indicating no pulse in the subject, and/or other information. In some implementations, the real-time feedback may comprise a recommendation to shock or defibrillate the subject. The recommendation to shock or defibrillate the subject may be determined responsive to a time elapsed since a start of chest compressions being at least three minutes (for example), the information in the signals from the sensor bank indicating ventricular fibrillation, the information in the signals from the sensor bank indicating no pulse in the subject, and/or other information. In some implementations, the real-time feedback may comprise a recommendation to inject the subject with epinephrine. The recommendation to inject the subject with epinephrine may be determined responsive to a time elapsed since a start of chest compressions being at least five minutes (for example), the information in the signals from the sensor bank indicating ventricular fibrillation, the information in the signals from the sensor bank indicating no pulse in the subject, and/or other information.
In some implementations, the subject may be receiving positive pressure ventilation during the code blue scenario. In such implementations, the real-time feedback may comprise a recommendation to adjust a ventilation pressure, a ventilation rate, and/or other ventilation parameters. The recommendation to adjust the ventilation pressure and/or the ventilation rate may be determined based on information in the signals related to a rate and depth of chest rise in the subject, for example.
In some implementations, generating the real-time feedback based on the information in the signals from the sensor bank may comprise a machine-learning analysis of the information in the signals from the sensor bank. The machine-learning analysis may comprise determining which future actions taken by caregivers during resuscitation would improve a likelihood of recovery from the code blue scenario by the subject. The machine learning analysis may comprise generating the real-time feedback based on the predictions and/or other operations. Operation 706 may be performed by one or more feedback processors the same as or similar to feedback processor 109 (shown in
At an operation 708, the real-time feedback may be provided to the caregivers during the code blue scenario. Operation 708 may be performed by a feedback interface the same as or similar to feedback interface 113 (shown in
